Question: For a simple - circular highway curve, the design speed is 1 0 0 km / hr and the superelevation rate that will be used

For a simple-circular highway curve, the design speed is 100 km/hr and the superelevation rate that will be used is 8%. The roadway has a width of 7.2 m (3.6 m per direction) and 2% normal crown. The point of intersection is at 57+34.23m. Superelevation will be introduced by rotation about the centerline and the superelevation runoff length will be split 2:1 between the tangent and the curve. The angle of intersection is 49\deg 52 and the radius that will be used is 1.2 times the minimum allowable and rounded-up to a multiple of 5 m. Find the stationing of the PC and PT and the stationing of the start and end of the tangent runout and superelevation runoff segments for introducing and removing superelevation.
